FCW Sub 22 9 3 LS
Cored duplex stainless steel wire for submerged arc welding
Description & applications
22% chromium - 9% nickel - 3% molybdenum - low carbon - nitrogen bearing weld metal
Attractive bead appearance without residual slag, outstanding slag release even in narrow gaps
High productivity and enhanced wetting properties compared to matching solid wires
Mineral additions to the core improve both mechanical characteristics and hot cracking resistance
Excellent X-ray soundness
Welds well with submerged arc flux(please consult us)
APPLICATIONS
Welding wrought, forged or cast duplex stainless steels
Duplex stainless steel cladding or weld overlay
Heterogeneous welding between duplex stainless steels and other stainless steels, CMn steels or low alloyed steels
